Hi , i know this sounds weird; last night around 12 midnight 10/3/15 my roommates went out to see lightning and became startled at a huge Black Helicopter that made NO sound flying above Edison St in Graton ..they said it was making no noise as it flew overhead heading in a Northwest direction they also say that it was flying very low...Please let us know if you heard or saw anything odd Saturday night..i know that my Neighbors Dog was going crazy barking for over 2 hours around 4:30 am & i also heard Coyotes howling a lot too...which could be from the Lightning...however the Silent Black Helicopter is very odd..Blessings e
